Can Mold Grow On Concrete
Wet conditions can cause mold and mildew growth on outdoor concrete like driveways, patios and steps. This growth usually occurs in damp or shaded areas that don’t receive a lot of sun or heat. Concrete, with all its nooks, crannies and pores, is actually a great incubator for mold. Wet, humid weather with warm temperatures only improves the growing conditions.
Kill Mold Safely With Vinegar
One of the safest DIY cleaners for killing mold is vinegar. Vinegar is a mild acid that doesnt smell particularly pleasant, but it does its job with mildew. However, vinegar does not kill 100% of mold types, so do your research or test a small area before committing to it.
- Baking soda and water solution
To clean mold with vinegar, liberally spray moldy areas with the undiluted white vinegar. Leave it on the moldy areas for at least an hour to penetrate and kill any roots embedded in the walls or floor.
Optionally, you may spray a solution of baking soda and water onto the vinegar-saturated areas to up its mold-killing power. Wipe down the surface with clean water to finish the job. White vinegar is an excellent , too!
If your basement smells like sewage, you may have a clog in the drain in the floor or in the toilet in the bathroom. Pour a mixture of vinegar, water, and baking soda into the drain to release the clog and quickly eliminate that sewage smell in the basement.
Repeat applications may be necessary if the clog does not break up the first time. However, after the clog clears, your basement will smell fresh and clean again.

Yes, the sheet rock should be removed. This is necessary not only to clean up the existing mold, but to implement the prevention measures.
First, you need to identify the source of the moisture. Three possibilities exist. 1.) Condensation from the warm interior air hitting the cold concrete wall. This typically does not happen behind a well sealed wall , but its possible.
2.) Vapor emissions through the concrete. This occurs when moisture moves through the concrete in vapor form, creating high humidity and saturation on the surface. In an uncovered wall, the water would simply evaporate into the air without causing an issue. The installation of the sheet rock traps the moisture, leading to mold growth. There are two solutions either keep the concrete exposed or install dimple board with a interior footing drain.
3.) Liquid water intrusion. Its possible youre having liquid water enter through the cold joint at the bottom of the wall. If this is the case, youll see more damage at the bottom plate/framing than higher up the studs. In most cases, the solution is an interior footing drain.

My Basement Wall Has Developed This In Recent Months This Is A Shared Wall Of A Twin Home But This Part Of The Wall Extends Past The Neighbor’s House And I Believe There Is Water Sitting On The Side Of The House Is This Mold
This is likely a combination of mold and efflorescence. Efflorescence occurs when moisture migrates through the concrete, picking up minerals along the way. Once the moisture reaches the surface, the water evaporates, leaving behind the mineral deposits. Because this is a product of water movement, often a small amount of mold growth is present as well. If the concrete wall is unfinished/uncovered, it will typically dry out on its own. However, youll need to fix the issue if you plan on finishing out this wall with framing, insulation, etc. The wall will inhibit dry out and lead to mold and rot damage to the framing.
Preventing moisture migration through a concrete foundation wall is accomplished by a combination of the following. 1.) redirecting downspouts away from the home. 2.) Installing a waterproof membrane on the interior side of the foundation wall. 3.) Installing an interior footing drain and sump pump at the base of the foundation wall.
Products And Tools Youll Need To Get Rid Of Mold In Basement Areas

- Sponge: On softer or smoother surfaces, a disposable sponge may be all thats needed to stop mold spots from becoming more significant problems.
- Mold stain remover: Though not essential for actually removing mold, youll likely find a dark stain on the material that the mold was growing on and youll want a product to remove it. Plus, removing the old stains can make sure that you recognize new mold growth later.
- Bleach: A solution of 1 cup of bleach to 1 gallon of water is enough to kill mold on surfaces, according to the CDC.

Its difficult to determine from the photo whether this is mold or efflorescence. An easy way to distinguish between the two is by flicking a bit of water on the surface. Efflorescence will dissolve in water, mold will just mat down a bit.
Either way, it likely indicates vapor emissions moving through the concrete. You can verify this by taping a piece of plastic to the concrete. Recheck this in a few days. If you find condensation on the backside of the plastic, you have a vapor emissions issue.
In a garage this is not a problem, as long as you keep sensitive items off the floor. The vapor will eventually evaporate from the surface. Do not install carpeting on any concrete showing signs of vapor emissions! This will lead to major mold problems.

Avoid Overloading Your Basement
Both an organic food source and moisture are important for mold to grow. Thats why its very important to cut the food source, along with lowering the humidity level in your basement. There is no better food for mold than the things you keep in your basement such as clothes, books, carpets and even the cardboard boxes in which you store all of those things.
Try eliminating everything that you dont need and avoid overstuffing your basement at all costs. Air must be able to flow and it cannot do so if every inch of your basement is covered. If you must use your basement for storage, and you are worried about mold, ensure that everything is properly dried and moved away from the walls. If there is a leak or a flood, take out everything that may have been in touch with water, dry it well and then put it back.

Diy Tips For Preventing Mold In The Basement
The experts at Mold Busters love to share what theyve learned over their years preventing, inspecting for and removing mold. The following are some trusty tips that will help you prevent mold in your basement:
Cleaning Mold On Basement Walls
Basements are usually dark areas, with poor ventilation, and tend to have higher than normal humidity. Under these favorable living conditions, mold will grow rapidly and thrive. Mold can come in a variety of colors, from black to white, and from blue to green. Molds color and type are not too important. What is important is getting rid of it. Successful cleaning of mold on basement walls can be difficult unless the causes allowing for mold growth are first addressed. Foundation leaks, caused by years of wear and cracks in walls and floors, along with condensation on plumbing and HVAC pipes and vents, tend to help maintain humidity levels that are higher than those normally found in above ground areas of the home. Another reason that cleaning mold on basement walls is difficult is due to the porous, rough surface of concrete. Its hard to reach deep into all the tiny crevices and pores.
When you see mold on basement walls, the mold is not growing on the concrete or the concrete blocks. Mold cannot eat concrete because concrete is not an organic substance. Organics, along with moisture, are some of molds requirements to grow to survive. Usually the mold is growing on dirt and dust or paint and wall coverings that contain organic components. Many paints are latex-based and latex is an organic compound.
